No clear video for this part yet. The steps cover it.

1Wash your hands, take the pump off and separate the milk collector, flange and silicone parts.
2Remove the old duckbill valve and check the other silicone parts for cracks, tears or stretching.
3Before first use, wash the new duckbill valve and boil it for 5 to 10 minutes, then let it air dry.
4Fit the new duckbill valve in the same place as the old one, so it sits snugly and lies flat.
5Reassemble the pump and check for leaks or low suction before pumping.
